What you get with this Offer
I will build a comprehensive API test suite for your REST API — using Postman with Newman for collection-based testing, or REST Assured (Java) for code-based test automation — covering positive response validation, negative case and error response testing, authentication and authorisation testing, schema validation, data-driven tests using test data files, and a CI/CD integration running the suite on every API deployment. API testing is the highest-value layer of the test pyramid — faster than UI tests, broader than unit tests, and directly validating the contracts that frontend and third-party integrations depend on — but only when it covers the error cases, authentication scenarios, and response schema validation that basic Postman collections frequently omit.
The test suite covers each endpoint with positive and negative test cases, authentication header testing (valid token, expired token, missing token), request body validation testing, response status code assertion, response schema validation using JSON Schema, response time assertion, and environment variable configuration for base URL and authentication. Newman or REST Assured CI/CD configuration is included.
Designed for API development teams, backend developers, and QA engineers who need a professional API test suite integrated into their delivery pipeline.
